图5是根据一示例性实施例示出的一种用于UCI传输的装置的框图。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权 利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的数据传输方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括终端和网络设备。终端通过无线资源与网络设备相连接，并进行数据的发送与接收。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例的无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和 具体设备形态不做限定。
相关技术中，终端与网络设备通信过程中，终端向网络设备发送UCI(uplink control information，UCI)。例如，针对物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，终端发送混合自动重传请求应答信息(Hybrid Automatic Repeat request Acknowledge character，HARQ-ACK)。再例如，终端向网络设备发送的调度请求(scheduling request，SR)，以请求调度相应的资源。其中，UCI承载在PUCCH中传输。
相关技术中，承载UCI的PUCCH与承载上行数据的PUSCH信道在时域上有重叠(overlapping)时，可以把UCI复用到PUSCH信道上。
在R15通信协议中，UCI复用到PUSCH的方式是：当承载UCI的PUCCH与一个或者多个PUSCH在时域上有overlapping时，会优先选择动态调度的PUSCH做UCI复用。如果没有动态调度的PUSCH，可以选择复用到半静态调度的PUSCH。如果有多个动态调度的PUSCH，则选择多个动态调度的PUSCH中PUSCH所在的载波索引(index)最小的PUSCH进行复用。如果一个载波上有多个PUSCH，则选择时域起始时间最早的PUSCH进行复用。
在R16通信协议中，引入了UCI和PUSCH的优先级，例如引入了HARQ-ACK/SR的高低优先级(HARQ-ACK/SR是UCI的一种)，以及PUSCH的优先级。针对具有高优先级的UCI和低优先级的PUSCH在复用时的一种处理方式为：直接发送高优先级的UCI，并丢弃低优先级的PUSCH。针对具有低优先级的UCI和高优先级的PUSCH在复用时的一种处理方式为：直接发送高优先级的PUSCH，并丢弃低优先级的UCI。
综上，相关技术中，在满足UCI复用到PUSCH信道上传输的通信条件，例如针对承载不同优先级UCI的PUCCH和具有不同优先级的PUSCH在时域上发生重叠时，并不存在如何将UCI复用到PUSCH的实施方案。在R17通信协议中，为了增强不同优先级业务的混合传输性能，提出需要讨论不同优先级的UCI/PUSCH复用的场景和方案。
本公开实施例提供一种UCI传输方法，在该UCI传输方法中，基于UCI和/或PUSCH的优先级，确定UCI复用的PUSCH。
本公开实施例中为描述方便，以第一优先级和第二优先级表征UCI和PUSCH的不同优先级。其中，第一优先级不同于第二优先级，第一优先级高于第二优先级。
可以理解的是，本公开实施例提供的UCI传输方法，可以在满足UCI复用到PUSCH信道上传输的通信条件下实施，不区分具体的通信场景。例如，在承载具有不同优先级UCI的PUCCH和PUSCH在时域上发生重叠时，采用本公开实施例提供的UCI传输方法。
图2A是根据一示例性实施例示出的一种UCI传输方法的流程图，如图2A所示，UCI 传输方法用于终端中，包括以下步骤。
在步骤S11中，基于UCI的优先级，确定UCI复用的PUSCH。
其中，UCI的优先级包括第一优先级或第二优先级。第一优先级高于第二优先级。
本公开实施例中，基于UCI的优先级，确定UCI复用的PUSCH，以实现具有不同优先级的UCI和PUSCH在时域上发生重叠时，确定复用的PUSCH。
本公开实施例中，UCI例如可以是PDSCH的HARQ-ACK信息，也可以是SR调度信息。
其中，UCI的优先级可以基于无线资源控制(Radio Resource Control，RRC)信息，或者下行控制信息(Downlink Control Information，DCI)信息确定。
一示例中，UCI为PDSCH的HARQ-ACK信息，UCI的优先级基于RRC信息，或者DCI信息确定。例如，UCI为动态调度的PDSCH的HARQ-ACK信息，UCI的优先级可以基于动态调度PDSCH的DCI指示。再例如，UCI为半静态调度的PDSCH的HARQ-ACK信息，UCI的优先级可以基于RRC层信令配置。
一示例中，UCI为半静态配置的SR调度信令。UCI的优先级基于RRC信息确定。
本公开实施例中UCI的优先级可以理解为是UCI的物理层优先级。
本公开实施例提供的UCI传输方法还可以包括确定UCI优先级的过程。
图2B是根据一示例性实施例示出的一种UCI传输方法的流程图，如图2B所示，UCI传输方法用于终端中，包括以下步骤。
在步骤S21中，确定UCI的优先级。
其中，UCI的优先级包括第一优先级或第二优先级。第一优先级高于第二优先级。
一示例中，基于RRC信息或者DCI信息确定UCI的优先级。
在步骤S22中，基于UCI的优先级，确定UCI复用的PUSCH。
本公开实施例中，基于UCI的优先级，确定UCI复用的PUSCH，以实现具有不同优先级的UCI和PUSCH在时域上发生重叠时，确定复用的PUSCH。
另一种实施方式中，本公开实施例提供的UCI传输方法，可以基于UCI和PUSCH的优先级确定UCI复用的PUSCH。
图3A是根据一示例性实施例示出的一种UCI传输方法的流程图，如图3A所示，UCI传输方法用于终端中，包括以下步骤。
在步骤S31中，基于UCI的优先级和PUSCH的优先级，确定UCI复用的PUSCH。
其中，UCI的优先级包括第一优先级或第二优先级。PUSCH的优先级包括第一优先级或第二优先级。其中，第一优先级高于第二优先级。
其中，本公开实施例中可以基于RRC信息或者DCI信息确定UCI的优先级。
本公开实施例中，可以基于RRC信息或者DCI信息确定PUSCH信道的优先级。例如，PUSCH为动态调度的PUSCH，则该PUSCH信道的优先级可以基于动态调度该PUSCH信道的DCI动态指示。再例如，PUSCH为半静态调度的PUSCH，例如配置授权的PUSCH(CG-PUSCH)，则该PUSCH信道的优先级可以基于RRC进行配置。
本公开实施例提供的UCI传输方法还可以包括确定UCI优先级和确定PUSCH优先级的过程。
图3B是根据一示例性实施例示出的一种UCI传输方法的流程图，如图3B所示，UCI传输方法用于终端中，包括以下步骤。
在步骤S41中，确定UCI的优先级和PUSCH的优先级。
其中，UCI的优先级包括第一优先级或第二优先级。PUSCH的优先级包括第一优先级或第二优先级。其中，第一优先级高于第二优先级。
一示例中，基于RRC信息或者DCI信息确定UCI的优先级。
一示例中，基于RRC信息或者DCI信息确定PUSCH信道的优先级。
在步骤S42中，基于UCI的优先级和PUSCH的优先级，确定UCI复用的PUSCH。
本公开实施例以下将对UCI复用PUSCH的实施方案进行示例性说明。
本公开实施例中PUSCH可以理解为是与承载UCI的PUCCH信道在时域上发生重叠的PUSCH。UCI复用的PUSCH也可以理解为是与承载UCI的PUCCH信道在时域上发生重叠的PUSCH。
一种实施方式中，与承载UCI的PUCCH信道在时域上发生重叠的PUSCH可以具有一个或多个。其中，与承载UCI的PUCCH信道在时域上发生重叠的PUSCH具有多个时，可以有不同的优先级。
其中，针对承载UCI的PUCCH信道与多个PUSCH在时域上发生重叠的情况，可以基于UCI的优先级和PUSCH的优先级，确定UCI复用的PUSCH。
一种实施方式中，承载UCI的PUCCH信道与多个PUSCH在时域上发生重叠，该时域上与PUCCH发生重叠的多个PUSCH具有第一优先级和/或第二优先级，第一优先级高于所述第二优先级。即，时域上与PUCCH发生重叠的多个PUSCH可以具有不同的优先级。
一示例中，时域上与PUCCH发生重叠的多个PUSCH具有第一优先级和第二优先级，UCI具有第一优先级(高优先级)，UCI复用的PUSCH具有第一优先级(高优先级)。即，对于高优先级的UCI优先复用到高优先级的PUSCH上，以避免UCI复用到低优先级的 PUSCH上被打孔或者丢弃的情况。
另一示例中，时域上与PUCCH发生重叠的多个PUSCH具有第一优先级和第二优先级，UCI具有第二优先级(低优先级)，UCI复用的PUSCH具有第一优先级(高优先级)。即，对于低优先级的UCI可以复用到高优先级PUSCH上，也可以理解为是优先复用到高优先级PUSCH上。
在本公开一种实施方式中，UCI具有第二优先级(低优先级)，终端需要确定具有第二优先级的UCI被配置为允许复用到具有第一优先级的PUSCH，当允许复用到具有第一优先级的PUSCH时，UCI才可以优先复用具有第一优先级(高优先级)的PUSCH。
一种实施方式中，本公开实施例中可以基于RRC参数配置具有第二优先级的UCI被配置为允许复用到具有第一优先级的PUSCH。例如，使用RRC参数分别配置低优先级的HARQ-ACK/SR允许复用到高优先级的PUSCH上。
又一示例中，时域上与PUCCH发生重叠的多个PUSCH具有第一优先级和/或第二优先级，UCI具有第二优先级(低优先级)，UCI复用的PUSCH也具有第二优先级(低优先级)。即，对于低优先级的UCI可以复用到低优先级的PUSCH上。
本公开一种实施方式中，UCI具有第二优先级(低优先级)，终端需要确定具有第二优先级的所述UCI被配置为不允许复用到具有第一优先级的PUSCH，UCI复用具有第二优先级(低优先级)的PUSCH。即，终端在确定不允许低优先级的UCI复用到高优先级的PUSCH的情况下，确定复用的PUSCH为低优先级的PUSCH。
一种实施方式中，本公开实施例中可以基于RRC参数配置具有第二优先级的UCI被配置为不允许复用到具有第一优先级的PUSCH。例如，使用RRC参数分别配置低优先级的HARQ-ACK/SR不允许复用到高优先级的PUSCH上。
在一种实施方式中，无论UCI的优先级为第一优先级还是第二优先级，该UCI都优先复用高优先级的PUSCH。即，UCI复用的PUSCH为具有第一优先级(高优先级)的PUSCH。
其中，可以理解的是，在低优先级的UCI不被允许复用高优先级的PUSCH的情况下，低优先级的UCI不能复用到具有第一优先级(高优先级)的PUSCH。
本公开实施例另一种实施方式中，针对承载UCI的物理上行控制信道与一个PUSCH时域重叠的情况，PUSCH具有第一优先级或第二优先级，第一优先级高于第二优先级。UCI复用的PUSCH为与承载UCI的物理上行控制信道时域重叠的PUSCH。
可以理解的是，本公开实施例提供的上述UCI传输方法，可以在满足UCI复用到PUSCH信道上传输的通信条件下实施，不区分具体的通信场景。一示例中，本公开实施例可以在承载具有不同优先级UCI的PUCCH和PUSCH在时域上发生重叠时，采用上述涉 及的UCI传输方法，以实现针对具有不同优先级的UCI和具有不同优先级的PUSCH提供复用实施方案，增强不同优先级业务的混合传输性能。
需要说明的是，本领域内技术人员可以理解，本公开实施例上述涉及的各种实施方式/实施例中可以配合前述的实施例使用，也可以是独立使用。无论是单独使用还是配合前述的实施例一起使用，其实现原理类似。本公开实施中，部分实施例中是以一起使用的实施方式进行说明的；当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。

其中，响应于承载UCI的PUCCH与多个PUSCH时域重叠，优先复用到具有第一优先级的PUSCH。
一种实施方式中，响应于承载UCI的PUCCH与多个PUSCH时域重叠，且UCI具有第一优先级，将UCI复用到具有第一优先级的PUSCH。
